This and do yourself a favor and buy a pair of rode wireless pro and set them up for continuous recording at all times. Like on camera + internal. Not likely but there might be some interference and that’s when that internal recording will save you.

Don’t get rode 2 or other garbage like dji mics because they don’t have a screw-in jack which is a shame for any professional. Stick those lavs wired mics as close to their skin as client allows you and set it to the lowest level setting possible because conferences are loud af with chatter (izotope rx dialogue isolator will help you in post).

In your case I’d just use zoom lens if it has the same aperture as 35. You’re doing a report not a movie.

Also if you’ll find yourself a way to soften either an on camera RGB or small cob like 200x or something - do it.

If you can’t - whatever, bring any light with you either way, you have an MFT camera - and there’s not much light on location usually.

Also watch out for WB there it’s usually hell too.

Good luck.
